[Tarantool-patches] [PATCH v2 2/2] xrow: reset parameters of decode_subscribe() to default

[Serge Petrenko via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

Nullify all the output parameters passed to xrow_decode_subscribe().

This should help us get rid of cases when some of the parameters were
left uninitialized when the SUBSCRIBE request didn't contain the
corresponding fields.

Follow-up #6034
